The MC9S12XEP100MAL is a 16-bit Microcontroller based on enhanced HCS12X CPU with CISC architecture operates at a maximum frequency of 50MHz. The device incorporates 1000kB internal flash, 64kB internal RAM, 4kB EEPROM, 16-channel 12-bit A/D converter and 91 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module, three multi-scalable controller area networks (MSCAN) CAN 2.0 A/B software compatible modules, eight serial communications interface (SCI) and three serial peripheral interface modules (SPI). The MC9S12XE family features an enhanced version of the performance-boosting XGATE co-processor which is programmable in C language and runs at twice the bus frequency of the S12X with an instruction set optimized for data movement, logic and bit manipulation instructions and which can service any peripheral module on the device.
